DESCRIPTION

Sodium, Potassium and Calcium Salts of Fatty Acids are salts formed by neutralizing fatty acids with sodium, potassium, or calcium, and differences in metal type influence solubility, hardness, and performance in specific systems.
Sodium salts tend to be more water-dispersible than calcium salts, potassium salts tend to be more soluble and are common in liquid soap chemistry, and calcium salts are typically more hydrophobic and are widely used as lubricants and release agents.
Sodium, Potassium and Calcium Salts of Fatty Acids provide lubrication by forming thin boundary layers that reduce friction between powders and equipment surfaces.

Sodium, Potassium and Calcium Salts of Fatty Acids reduce caking by coating particles and reducing moisture-driven bridging, and this is why Sodium, Potassium and Calcium Salts of Fatty Acids are effective flow aids in dry blends.
Sodium, Potassium and Calcium Salts of Fatty Acids performance depends on particle size, surface area, and moisture content, and finer grades can provide stronger effects at lower dosage but may increase dusting.
Sodium, Potassium and Calcium Salts of Fatty Acids should be selected based on purity and intended use, especially for food and pharmaceutical grades where contaminant limits and source oils matter.

Sodium, Potassium and Calcium Salts of Fatty Acids should be stored in tightly closed containers in a cool, dry place to prevent moisture pickup and contamination.
Sodium, Potassium and Calcium Salts of Fatty Acids powders can generate dust, so dust control and appropriate PPE are recommended during handling.
Sodium, Potassium and Calcium Salts of Fatty Acids should be used according to applicable regulations and specifications for the intended market and product category.

FIRST AID

Inhalation:
Move to fresh air if dust is inhaled.
Seek medical attention if respiratory irritation persists.
Avoid breathing dust during handling and powder transfer.

Skin Contact:
Wash with soap and water after contact.
Remove contaminated clothing and wash before reuse.
Seek medical advice if irritation develops or persists.

Eye Contact:
Rinse cautiously with water for several minutes.
Remove contact lenses if present and easy to do, then continue rinsing.
Seek medical attention if irritation persists.

Ingestion:
Rinse mouth with water.
Seek medical attention if discomfort occurs or if a large amount is swallowed.
Never give anything by mouth to an unconscious person.

Note to Physicians:
Treat symptomatically.
No specific antidote is required.
Provide supportive care as needed.

HANDLING AND STORAGE

Handling:
Use appropriate PPE including gloves and safety glasses, and use dust protection as needed.
Avoid generating dust and avoid inhalation of fine powder.
Use controlled addition to prevent dust clouds and improve blend uniformity.

Ventilation:
Use local exhaust or general ventilation where dust may be generated.
Maintain good airflow during weighing, charging, and blending operations.
Minimize airborne particulate accumulation in enclosed areas.

Storage:
Store in tightly closed containers in a cool, dry place.
Protect from moisture to prevent caking and maintain free-flowing behavior.
Keep containers properly labeled and protected from contamination.

Spill and Leak Procedures:
Sweep up spilled material and avoid dust generation.
Collect into suitable containers for reuse or disposal according to local regulations.
Clean residues with wet wiping if needed to reduce airborne dust.

Handling Precautions:
Select the correct fatty acid salt type and grade because sodium, potassium, and calcium salts differ in solubility, hydrophobicity, and release performance.
Control dosage and mixing time in tablet manufacture because over-lubrication can reduce tablet hardness and slow dissolution.
Rotate stock using FIFO practices to maintain consistent quality and predictable processing performance.
